Restore Full Electrical Control to Your GM Vehicle
Are you experiencing frustrating and unpredictable electrical problems in your Chevrolet Equinox, GMC Acadia, or another compatible GM vehicle? Issues like flickering lights, malfunctioning power windows, erratic dashboard warnings, or even a no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s electronic accessories, and when it malfunctions, it can create a cascade of confusing and disruptive problems. This isn’t just an annoyance; it can be a significant safety concern.
This replacement Body Control Module, part number 20864768, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation. We take the guesswork and hassle out of the repair process. Unlike a generic module from a dealership or parts store, this unit arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We load it with the latest, most stable software updates directly from GM, ensuring optimal performance and compatibility right out of the box. This means no expensive trips to the dealer for programming, saving you both time and money.
From the Diagnostic Bay
We once had a 2008 GMC Acadia come in with the most bizarre symptoms. The customer reported that sometimes the radio would turn off, the interior lights would pulse, and the liftgate would open on its own. We checked the battery, alternator, and all the main grounds—everything looked perfect. After hours of chasing wires, we finally hooked up a high-end scanner and monitored the BCM data stream. We saw garbled communication and voltage drops that made no sense. On a hunch, we swapped in a known-good, programmed BCM. Instantly, every single ghost in the machine vanished. It was a stark reminder that a failing BCM can make a perfectly good vehicle act completely possessed.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Dashboard lights flickering or warning lamps staying on for no reason (ABS, Airbag, Check Engine).
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Key fob not responding or security system acting erratically.
- ✔ Horn honking randomly or not working at all.
- ✔ A/C and heater controls behaving unpredictably.
- ✔ Vehicle failing to start, accompanied by a rapid clicking sound from the dash.
- ✔ Communication errors with diagnostic scan tools.

The module you receive is a direct-fit replacement, making the physical installation straightforward for a DIYer or any professional mechanic.
Installation and Post-Install Notes
While this module is designed for a plug-and-play installation, some vehicles may require minor post-installation procedures, known as relearns. This is a normal part of replacing a major electronic component.
- Airbag System Sync: In some cases, the new BCM may need to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). If your airbag warning light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: To ensure proper function of your brake lights and traction control system, a brake pedal position sensor recalibration might be necessary. This can also be performed with a compatible diagnostic tool.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for detailed instructions for your exact model.

Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic systems. This includes power windows, door locks, interior and exterior lighting, security systems, climate controls, and the instrument cluster, among others.
Is this BCM difficult to install?
The physical replacement is typically straightforward. On a 2007-2009 Equinox BCM, it is located in the center dash area. The main benefit of our service is that the module arrives pre-programmed, eliminating the most difficult step. Most DIYers with basic tools can perform the physical swap, though some post-install relearn procedures may require a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship the part until we have your VIN.
Will I need to do any programming myself?
No. The module is delivered fully programmed to your VIN with the latest GM software. It is ready to be installed upon arrival. The only additional steps that might be needed are the ‘relearn’ procedures mentioned, such as for the airbag system or brake pedal sensor, which are sync procedures, not programming.
What happens if the airbag light comes on after installation?
This is a known possibility and indicates that the new BCM needs to be synced with the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade scan tool to resolve this and turn off the light.
Does this part fit vehicles other than the Equinox?
Yes, absolutely. This BCM fits a very wide range of GM vehicles, including the GMC Acadia, Chevrolet Traverse, Buick Enclave, Cadillac DTS, Chevrolet Impala, Express and Savana vans, and many more. Please refer to the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
